Testing Method: SET2DIL

SET2DIL is a method of measuring Differential Insertion Loss (SDD21) using a single-ended TDR or VNA measurement, lending the name Single Ended Transmission 2 Differential Insertion Loss. It was created by Jeff Loyer and Richard Kunze in the late 2000s.

The single-ended solution was an departure from other loss testing methods that required 4 measurement ports and therefore 4 test points to be probed while measuring SDD21. This promised a simpler solution that could be utilized by manufacturers to ensure their manufacturing process was within the tolerances of attenuation as set by the circuit board designer.

ACCU-Prober with SET2DIL

Introbotix was approached in 2010 by Intel Corporation to develop a commercially viable production product for measuring SET2DIL. Utilizing the ACCU-Prober platform, Introbotix released the ACCU-Prober with SET2DIL in April 2011. The ACCU-Prober for SET2DIL delivers measurements at 20GHz with results exported in the industry-standard comma delimited text format. It is widely used by printed wiring board manufacturers worldwide.

ACCU-Prober HF30 with SET2DIL

Responding to the industry need for testing at ever increasing frequencies, the ACCU-Prober HF30 was released in late 2013. This higher frequency configuration utilizes the same method, software, and production-friendly hand probe as the original but with measurements up to 30 GHz.
